ABSTRACT:
In a disc brake of the spreading type, angular movement of the pressure plates to apply the brake is effected by a brake-applying member which co-operates with at least one of the balls comprising a rolling actuator body and located in complementary opposed recess in the two plates. The member may comprise a wedge disposed between a pair of balls and radially displaceable to separate the balls. Alternatively the balls may be received in openings in the inner ends of a pair of toggle links, or in a fitting or other member which can be withdrawn from the brake in a radial direction. In another construction a ball is received in an opening in a bell-crank lever of which one arm reacts against one of the pressure plates.
